The week in pictures: 11 January 2013

Two men spend 24 hours without food or water while trapped inside two large blocks of ice. Cui Deyi and Wang Baoyu were dressed only in shorts. The temperature inside the blocks was measured at -5 degrees centigrade (23 F). They emerged 24 hours later to the cheers of spectators who had gathered to witness the feat. Both men were found to be in good condition following their ordeal. They had both pulled off impressive cold-water stunts prior to this one: Cui holds a world record in winter-swimming, and Wang, a dentist by profession, holds several records for low-temperature feats of survival.Picture: HAP/Quirky China News / Rex Features
